Earlier this month Arsène Wenger was asked at his press conference about the rumours of Rosický leaving Arsenal in January. And the Frenchman dismissed the rumours and said this below.

“Rosicky is at Arsenal and he remains at Arsenal,”

Rosický still has something to offer Arsenal, he’s an experience player who’s been very unlucky with injuries in previous seasons. But he isn’t getting any younger and I wouldn’t rule out the Czech midfielder leaving Arsenal in the summer.
